To all whom t may concer/n.'

Be it known that I, LINDLEY S. LAWSON, a citizen of the United States, and resident of Homestead, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Water- Heaters, oit' which the following is a specifi cation. v y

This invention. relates to' a water heater for use in connection with stand boilers and other containers, the apparat-us including a gas-heated coil through which the boilercontained water' circulates, and one' object is to provide improved apparatus of compact form, the casing'of which' incloses a gas burner having an inlet at one side of the casing whereby the burner and its connections are more conveniently accessible than in those forms of heaters wherein the bu'rneninlet extends downwardly beneath the casing.

A further purpose is to provide improved means for removably supporting the circu lation coil and the burner within the casing; also to so construct the .casing that the cou-.

pling-carrying lower extremity of the coil mayibe 1 eadily inserted, with means for closing the opening through which the coupling passes.

In `the accompanying drawings, Figure 1` is a View of a heater embodyingthe invention, the same being shown partly in eleva-- tion with the door-forming portion of the casing open, and partly in vertical section. Fig. 2 is a sectional 'plan taken on line of Fig. 1, the burner inlet being shown in section. Fig. 3 is a sectional elevation of one` side ot the upper portion of the heater taken at right angles to Fig. 1, and Fig. 4 is a similar view of the lower portion of the heater taken on line of Fig. 1.

Referring to the drawings, the upright in` closing casing is divided vertically, 2 designating the portion thereof which constitutes e ing on lugs 8 at the inner side of the casing.

f' The coil is conined on the supporting lugs Application led November 13, 1914. Serial No. 872,741.

by a clip 10 which is removably secured tol` the inner side of the casing between lugs 11 by bolt 12. Said clip engages one of the lower convolutions of the coil, and a similar clip 10 engages one of the upper convolutions, so that the coil of relatively thin copper tubing is firmly yheld in place.

'The coil is preferably of spool form, being of smallest diameter midwayits ends, and in the plane of this srnallest-diameter portion part 2 of the casing is formed with the encircling inwardly-projecting rib or 4vane 2', and door part 3 with a corresponding rib 3. When the casing is-closed ribs 2 and 3 comprise a baie for `the ascending heat currents, directing them inwardly toward the coll and thereby increasing the efficiency of the heater.

The lower extremity 7 of the coil is itted with a coupling element 18 which is ordinarily applied thereto'before the heater is assembled, and in order that the coil may be inserted in the casing the support-forming portion 2 thereof is fqrmed with' an opening 141- of sufiicient size to pass the coupling, the opening being closed by the gate or plate 15 which fits around coil extremity, Figs. 1 and 4.

The hollow burner 16 is of general starform with air passages 17 between its armlike branches, also a central air passage 18.' The mixer tube 19 projects laterally from the vburner body through a socket-like opening 20 near the bottom of one edge ofcasing part 2. The connections for the burner are thus located at one side of the heater and are more conveniently accessible than with the lburner connections extending upwardly fronn beneath the .heater as has heretofore been customary. Also, with the improved construction the heater may stand on the Hoor or be arranged closer thereto than is possible with the old form of burner connections. The mixer tube also coperates'with burner lugs 21 and 22 in supporting the burner within the casing. lug 21 being adapted to enter a notch or recess 21 in the vertical edge of casing part 2 opposite the mixer tube, and lug 22 being adapted to pass through an opening 22 in said ca 'ing part beneath the coil extremity 7', Figs. 2 and 4. Lug22 is apertured to receive a cotter 23 which holds the burner in place when the casing is opened as in Fig. 1; Mixer tube 19 and lug 21 being at the juncture of the casing sections, when door sectlon 3 is opened it is only necessary to displace Cotter l and the burner may be removed in its entirety. And with the door v open the'circulation coil may be readily taken out by removing gate 15 and releasing clip l0, crown 4 being released by removing its securing bolts 4 to permit withdrawal of the upper extremity of the coil extremity carrying coupling,1 element 13'.

A pan 24 is suspended beneath the burner for catching condensate which drips from the coil, the condensate evaporating.;l before the pan can overflow. The pan may be conveniently supported' by bolt which secures it to lug 26 projecting in the burner air passage 18. Openings 2% in the pan admit air in sufficient amount for the burner. The drip pan thus mounted iis in efect a portion of the burner, being inserted and removed therewith.

'The several novel features herein described combine to produce a heater of simple and compact construction in which the several parts are readily accessible and with the parte conveniently arranged for assem- Ibling and for taking apart.

I claim: 1. In a water heater, the combination of an upright casing adapted to open at one.v

`neatli the coil, the burner having a lateralljvf disposed fuel inlet and the casing formed the pan formed with vertical air passages of such ar a as to supply the requisite amount of air to theburnera ln a water heater, the combination of:

a vertically divided upright Casing: withone f portion thereof comprisinga coil support` and the other portion comprisingf a door,

coil-sustaining lugs spaced apart and proi jecting from the inner wall of the coil-supporting casing,` sectipp, an upright circulation coil adapted tolbe entered through.; the open side of said casing section and rest on the supporting lugs thereof. and clips reniovably secured to the inner side of said casing section and embrace the upper Aand lower portions of the coll and hold the latter in position on said lugs. and a burnerl supported beneath the casing.

4. Ina watcrheater. the combination of` a vertically divided casingwith one section thereof eomprising a support and withl the other section comprisingT a door, the support-forming portion of the casilncf lformed `with a passage which intersects thc joint between the two portionsof the casing." a circulation coil adapted to be sustained within the support-forming portion of the casing-r. and aburner adapted to be entered in the silpport-forininfsv `portion of the casingr when thedoor portion thereof is open.

the burner having a laterally extendingy mixer tube which is adapted` to be entered iii said joint-intersecting oilieningl` in the casin;Y and be confined therein when the doorforming;V portion of the casing' is closed..

In testimoniY whereof. l atix my signature in presence of Vtwo \`i'ituesses.
